Administration isn't really a feature since there's no ))AdministrationDoc(( but instead many *Admin pages.
However there have been some problems about it.
If some administration pages have to be changed/added, if some options have to be added or transfered from one page to another, requests can be placed here.
You can also report bugs in administration if you find some.
This is where new features being developed and only in CVS are documented. When the CVS becomes RC/official release, the info in the CVS docs is transferred to update the official docs (FeatureXDoc).
Where ideas can be exchanged, debated, etc. Interested people can subscribe to the wiki page and/or to these forums as they would a mailing list.
